Read 4 channel analog inputs by TCP or RS485 protocol - admin - 04-15-2022
1: Read 4 channel analog inputs by TCP command：
Send: RELAY-GET_AI-255
Feedback: RELAY-AI-ALL,A0,A1,A2,A3,OK
A0,A1 analog input range: DC0-5V
A2,A3 analog input range: 4-20mA
example:
A0 and A1 connect with 3.3V , will feedback:
RELAY-AI-ALL,330,330,0,0,OK
A2 and A3 connect with 10mA sensor , will feedback:
RELAY-AI-ALL,0,0,455,455,OK
--------------------------------------------------------------
2: enable/disable analog inputs by TCP command:
Send: RELAY-AI_REPORT-255,1 //Enable analog input AUTO feedback
Feedback: RELAY-AI_REPORT-255,1,OK
Send: RELAY-AI_REPORT-255,0 //Disable analog input AUTO feedback
Feedback: RELAY-AI_REPORT-255,0,OK
---------------------------------------------------------------
3. Read 4 channel analog inputs by MODBUS RS485
01 03 01 2C 00 04 CRCH CRCL
Feedback: 01 03 08 A0 A1 A2 A3 CRCH CRCL
01:RS485 address ID
01 2C=300 register address
00 04 register number
example:
if A0 connect with 3.29V
Send: 01 03 01 2C 00 04 84 3C
Feedback: 01 03 08 01 49 00 00 00 00 00 00 8C DF
01 49 =329 = 3.29V
if A1 connect with 3.31V
Send: 01 03 01 2C 00 04 84 3C
Feedback: 01 03 08 00 00 01 4B 00 00 00 00 30 08
01 4B =331 = 3.31V

Thanks for the answer!
BUT it must be possible to get a complete Modbus address list, or a complete list of all TCP commands and at least instructions how to handle payload on Modbus.
Are you seriously giving me examples with TCP that contain Chinese characters?
This means that i can expect that you will not receive appropriate help if i have problems in use.
I can't even read a manual with a complete description of all the options?
Rarely have I read such a praise for a product.
I find it out, here the doku for my questions Doku
